Abstract: High density multitrack magnetic heads are batch- fabricated from a stack of non-magnetic wafers (10) which are photolithographically processed to provide lands (62a-d, 88a-b) and recessed structures (64, 90) in the wafers. Magnetic layers (76, 94) are deposited within the recessed structures and, within some of the grooves, coils (70) inductively coupled to the magnetic layers are also deposited. The combined thickness of the magnetic layers and coils or of the layers themselves is less than the depth of the recessed structures, with the wafer lands serving both to provide track-to-track spacing and to protect the magnetic layers from magnetostriction producing stresses. A selected number of grooved wafers are bonded together, sliced and then processed as generally done in the art to produce a plurality of multitrack magnetic heads.

Abstract: A method of fabricating a field effect transistor comprising the steps of forming an active layer (5) of semiconductor material (GaAs) over a surface of a first substrate (2) of semiconductor material (GaAs), applying a second substrate (6) of insulating material, eg glass, over the surface of the active layer, removing the first substrate so that the active layer is now supported on the insulating second substrate, and forming source, drain (9,10) and gate (121 electrodes over the free surface of the active layer. To facilitate removal of the GaAs first substrate by selective etching, a buffer layer (1) of GaA1As resistant to the GaAs etchant, may be formed between the active layer and the first substrate, which buffer layer is removed, following removal of first substrate, using a selective etchant to which the GaAs active layer is resistant. The technique is particularly applicable to high frequency PETs requiring a very thin active channel region interfaced to a substrate having good insulating properties.

Abstract: Appareil de therapie visuelle comprenant des affichages espaces l'un de l'autre afin de montrer une sequence d'images a un patient les regardant. Cela fournit la faculte de varier le taux d'affichage des images et de prendre note de la production de cas speciaux et la detection ou le manque de detection de ceux-ci par le spectateur. Dans une mise en oeuvre, deux affichages (10, 12) sont mis en place, generalement, en ligne, l'un pres, et l'autre eloigne, du spectateur. Chaque affichage montre, au hasard, une serie d'images differentes qui, alternent image par image, avec la serie d'images montrees par l'autre affichage. Le spectateur observe alternativement les affichages proches et eloignes, executant ainsi un exercice optique et signale a l'appareillage lorsqu'un cas visuel special se presente, par exemple l'exposition successive de la meme image par les deux affichages. Dans une autre mise en oeuvre, deux affichages sont disposes cote a cote, et sont observables simultanement par le spectateur. Les affichages montrent les images en meme temps et un cas visuel special survient lorsque les deux images cote a cote, mises en convergence par les yeux du spectateur (ceci constituant l'exercice optique), forment une seule image composite reconnue par le spectateur. L'espacement des affichages cote a cote est variable.

Abstract: Un rotor (11) pour un frein a machoires (10), le rotor etant monte sur un organe cylindrique d'adaptation (26). Les rotors anterieurs, decoupes dans des plaques d'acier, etaient couteux a cause du dechet excessif, et lorsque les rotors etaient en contact avec les patins de frein, ils produisaient un bruit et des vibrations indesirables. La solution a ce probleme est de fabriquer le rotor en enroulant une bande d'acier en forme de disque, la discontinuite radiale entre les spirales adjacentes agissant comme une barriere aux vibrations et aux bruits. Le rotor (11) comprend une bande metallique enroulee (54) ayant une section rectangulaire avec des surfaces en bordure (55, 56) alignees pour definir des faces de frottement engagees par les supports de garniture de frottement (43, 45) du frein et diminuer les vibrations et le bruit pendant le freinage.

Abstract: The disclosed adhesive products include a carrier sheet bearing a polymeric film and an adhesive layer, overlying the film as in dry transfers or underlying the film in prodcts such as wire markers and other labels, or there may be adhesive laxers both over and underneath the polymeric film. A constituent initially contained in the polymeric film layer migrates into an ordinarily non-tacky precursor of the adhesive layer, thereby rendering the precursor tacky. The precursor layer becomes adhesive only where it is opposite the polymeric film, being non-tacky outside the area of the film. In important applications, the common area of film and adhesive layers does not cover the whole carrier sheet. Both the adhesive precursor layer and the polymeric film may include portions extending outside the common area.

Abstract: A medical treatment system provided with a safety device which prevents laser beams from being unnecessarily projected on a normal coeliac tissue around an affected coeliac region requiring medical treatment from a laser knife apparatus. When the operator approaches an eyepiece and is at a prescribed distance therefrom, then the safety device removes a mirror from a path of laser beams, enabling laser beams to be brought into a laser knife probe when a foot switch is closed. An infrared ray detector is provided in the eyepiece. When the operator approaches the eyepiece and is at the prescribed distance therefrom, an output signal from the infrared ray detector will be at a prescribed level. As a result, a solenoid controller is actuated to energize a solenoid. The mirror is removed from a path of the laser beams by the energized solenoid. Unless the operator approaches the eyepiece, the mirror remains in the path of laser beams, thereby preventing laser beams from being brought into the laser knife probe.

Abstract: An electrolytic display device, specifically an electrochromic display based on viologen, employs metal ions in solution to catalyse the reduction of display material at the display electrodes. The metal ions are deposited faster than the display material and subsequently chemically reduce this material. Thallium (I) as the metal catalyst in combination with an oxy-anion of phosphorus accelerates the display reaction without causing undesired precipitation from the solution. Cadmium (II) in combination with sulphate anions is also an effective catalyst. Either a greater amount of display material may be deposited than without the catalyst or the same amount deposited in a shorter time.
